It is the first center for visual processing in the larval brain. It is largely surrounded by the outer optic anlage at earlier developmental stages and becomes sandwiched between the developing proximal medulla and the inner optic anlage by third instar. It is incorporated into the adult optic lobe as the accessory medulla. VFB:FBbt_00048289 FBbt:00048289 larval sensory compartment sensory perception of light stimulus
